Classical dynamical density functional theory: from fundamentals to applications

M te Vrugt, H Löwen, R Wittkowski - Advances in Physics, 2020 - Taylor & Francis
Classical dynamical density functional theory (DDFT) is one of the cornerstones of modern
statistical mechanics. It is an extension of the highly successful method of classical density …

A new class of efficient and robust energy stable schemes for gradient flows

J Shen, J Xu, J Yang - SIAM Review, 2019 - SIAM
We propose a new numerical technique to deal with nonlinear terms in gradient flows. By
introducing a scalar auxiliary variable (SAV), we construct efficient and robust energy stable …

Structure of electric double layers in capacitive systems and to what extent (classical) density functional theory describes it

A Härtel - Journal of Physics: Condensed Matter, 2017 - iopscience.iop.org
Ongoing scientific interest is aimed at the properties and structure of electric double layers
(EDLs), which are crucial for capacitive energy storage, water treatment, and energy …

Unconditionally positivity preserving and energy dissipative schemes for Poisson–Nernst–Planck equations

J Shen, J Xu - Numerische Mathematik, 2021 - Springer
We develop a set of numerical schemes for the Poisson–Nernst–Planck equations. We
prove that our schemes are mass conservative, uniquely solvable and keep positivity …

Anisotropic self-assembly from isotropic colloidal building blocks

M Rey, AD Law, DMA Buzza… - Journal of the American …, 2017 - ACS Publications
Spherical colloidal particles generally self-assemble into hexagonal lattices in two
dimensions. However, more complex, non-hexagonal phases have been predicted …

Adaptive brownian dynamics

F Sammüller, M Schmidt - The Journal of Chemical Physics, 2021 - pubs.aip.org
A framework for performant Brownian Dynamics (BD) many-body simulations with adaptive
timestepping is presented. Contrary to the Euler–Maruyama scheme in common non …

Controlled self-assembly of periodic and aperiodic cluster crystals

K Barkan, M Engel, R Lifshitz - Physical review letters, 2014 - APS
Soft particles are known to overlap and form stable clusters that self-assemble into periodic
crystalline phases with density-independent lattice constants. We use molecular dynamics …

Interfacial self-assembly of SiO 2–PNIPAM core–shell particles with varied crosslinking density

M Ickler, J Menath, L Holstein, M Rey, DMA Buzza… - Soft Matter, 2022 - pubs.rsc.org
Spherical particles confined to liquid interfaces generally self-assemble into hexagonal
patterns. It was theoretically predicted by Jagla two decades ago that such particles …

Forming quasicrystals by monodisperse soft core particles

M Zu, P Tan, N Xu - Nature communications, 2017 - nature.com
In traditional approaches to form quasicrystals, multiple competing length scales involved in
particle size, shape, or interaction potential are believed to be necessary. It is unexpected …

Three-dimensional icosahedral phase field quasicrystal

P Subramanian, AJ Archer, E Knobloch… - Physical Review Letters, 2016 - APS
We investigate the formation and stability of icosahedral quasicrystalline structures using a
dynamic phase field crystal model. Nonlinear interactions between density waves at two …
